Unfortunately I was in the middle of nowhere and had to ride 30km back to civilization, which has resulted in some damage to the carbon which the insert was bonded to. Not been able to source JB Weld in Thailand, is there any other product name that it goes under that I can check?

Got a puncture during my regular Sunday morning ride, popped the wheel out and fixed the flat, putting the wheel back in the metal insert just fell off! Been told that it means the frame is toast, but will confirm with the specialized dealer later in the week

Wonder if a situation like this would be covered by Giant's lifetime warranty or they would argue misuse/abuse............

For me it's hard to say either way, in my case I did nothing different than normal and it broke off, bike has done around 15000km so I don't think they can argue it's normal wear and tear either, as my friends has done 50000km no problem.

Right then. Metal insert from other side dropped off this morning when changing the wheel. Not from trainer, just after normal ride. Came out clean, just like moonoi's. Will upload pic later. So seems it's just a bad glue job like guys we're saying earlier. What's the absolute strongest glue I can use to glue it back on? Still haven't got part for original side yet, Workswell ignored my second email

Side note, can cold weather affect the glue? Riding around 0 to -2 recently..

Can you use the freshly fallen off piece to get a couple of new bits made so you have some spares, and a correctly shaped piece to start with for fitting to the other side? (Some gentle filing and trimming to get it round the screw head)

Any two pack epoxy should be strong enough if the surface is cleaned and prepped properly.

I would look for something like a Loctite Hysol E-120 or E-20 epoxy. Make sure you give some tooth to the stainless bonding area with a file, perhaps a little on the carbon area, then clean both thoroughly with Acetone before bonding. Then leave it alone until it is fully cured.
